CFM provides two methods for creating MEPs: autogenerated and explicit. You cannot use both. You must choose one or the other. Use the procedures in this section to configure autogenerated MEPs that eliminate the need to configure an MD, MA, and MEP ID to create a MEP.
Previous explicit CFM configurations of MDs, MAs and MEPs on SPBM B-VLANs continue to function. However, if you want to enable the autogenerated commands, you must first remove the existing MEP and MIP on the SPBM B-VLAN. The switch only supports one MEP or MIP on the SPBM B-VLAN, either explicitly configured or autogenerated.
